Angular vs React: Quick Comparison

Here is a comparison between React and Angular that can help you choose the best technology according to your needs.

Performance

In terms of performance, there is one big difference between Angular and React. While React uses virtual DOM(document object model), Angular uses real DOM. The document object model allows the developers access to document layout, content, and even structure. The issue with real DOM is that it makes the process slow when dealing with a lot of data requests.

Take the case wherein you want to update the details of a user’s profile, say birth date. With real DOM, instead of changing just some information, the system updates the entire tree structure of HTML tables until it reaches the data that is to be edited.

A virtual DOM, on the other hand, makes the changes without the need to rewrite the entire HTML doc. Thus the rendering in the case of a virtual DOM is much faster, and this translates into a faster performance as compared to a real DOM. Hence if you hire reactjs developers to build your app, then you can expect a better performance from the app.

Data binding

Data binding is concerned with synchronizing the data between business logic and UI. The difference between Angular and React is that while Angular uses both one-way and two-way data binding, React.js uses only one-way binding.

In one-way data binding, the data flows only in one direction, that is, from typescript file to html file. On the other hand, in two-way data binding, the data flow is bi-directional, meaning the data can flow in between typescript file and html file in both directions.

The one-way data binding makes the code more stable and also makes debugging the app much easier as compared to two-way data binding. The difference between Angular and React is that while Angular can use both one and two-way data binding, React.js uses only one-way binding.

With Angular, the developers find working with one and two-way binding more simple as compared to working with React.js.

Component architecture

For building UIs, React.js has an approach of breaking the UI down into components. With React.js, the developers will need to build components that manage their own state. Then they have to structure these components together to build a more complex user interface.

With React.js, the developers will require supporting tools. We have named a few below.

• Redux
• Babel
• Webpack

Angular, on the other hand, is a full-fledged framework that comes with many out-of-the-box features like:

• RxJS
• Angular CLI
• Angular Universal

Flexibility and freedom

React provides the developers with a lot of freedom to choose the libraries, architecture, and tools according to their requirements. Using React, the developers can build a highly customized app. Angular, on the other hand being a framework offers the developers a limited amount of flexibility in terms of the choices of libraries and tools available.

Thus, React offers better flexibility and freedom as compared to Angular.

Development speed and productivity

In the React vs. Angular battle of productivity, Angular gains the upper hand. Angular provides a much better development experience thanks to some of the key features of Angular like

• Clean coding
• Built-in process to solve issues
• Ability to produce components and services with one-line commands

With React.js, the development speed and productivity are affected as there are a lot of third-party libraries involved. React.js developers need to put thought capital into selecting the best architecture and tools for developing the app.

The toolkit for React.js apps varies from project to project. This creates an issue when the project is handed over to a new team of developers, as the new developers might not be familiar with the toolkit used to build that particular project.

Learning curve

When we compare Angular vs React.js on the ease of learning parameter, we find that the learning curve of Angular is steeper as compared to that of React. Angular has a complex component management system, and the developers need to have a good grasp of various concepts like dependency injection, typescript, and RxJS.

The developers need to learn TypeScript for Angular and while TypeScript is similar to JavaScript, the developers will still need to invest some time learning the language. Similarly, RxJS will also require some effort on the part of developers to learn.

Angular is a framework that is developing consistently. The constant changes in Angular mean that the developers need to remain updated with the changes in the Angular ecosystem.

While selecting the Angular developers, you need to ensure that your Angular developers are always updated with the latest developments in Angular. If you want to gain in-depth information about hiring Angular developers, then read our blog on how to hire Angular developers.

Developers can easily learn React. if they know JavaScript. React. has a wide range of useful resources for new developers. These resources make it easy for the developers to understand the framework and stay updated with every React update.

Componentization

The idea behind componentization is to isolate the front-end features into components that are easy to reuse, test and secure. Componentization makes the app easy to scale according to the
dynamic market demands.

Both react and Angular are component based architectures. The difference lies in how both these technologies achieve componentization.

With Angular, the components are functions that allow a directive or service to be modified before usage. The developers can tell if a class is a module or a component. Thus, the developers can pull the necessary metadata together to determine the best way to render a view.

React.js, on the other hand, chooses a way of developing component trees. The React library has functional programming in which the component definitions are declarative.

In terms of componentization both Angular and React are component-based architectures. Hence they fare equally well on this parameter.

Backward compatibility

The developers love to work with a framework wherein there is a possibility to update the architecture and add new modules and libraries. With Angular, it is impossible to directly jump from Angular 2.0 to Angular 7.0.

One of the key features of React is its full backward compatibility. The developers can add different releases of libraries to the app and update the old ones. React.js proves to be the better choice when the nature of the project is such that you need to keep on adding new features in a step-by-step manner. Backward compatibility happens to be one of the top reasons to choose React.js for front-end development.

Thus when we see React.js vs. Angular in terms of backward compatibility, React.js emerges as the clear winner.

Scalability

Whenever you choose technology for app development, always keep in mind the scalability aspect. This is because you do not want to be stuck with an app that is not scalable beyond a certain point.

It is easy to build a maintainable architecture with server-side rendering using React.js. Angular has all the core features the developers require for scaling an existing app.

Thus when we see React vs. Angular on the scalability aspect, we find that both of them allow the developers to build highly scalable apps.

Angular vs React: When to choose?

There are certain instances where angular is the best choice while react is preferable in other situations. We have mentioned below some conditions where you should choose React and some conditions where you should go for Angular.

When to use React?

You can choose React.js in the following conditions.

• Your team has a good grasp of JavaScript, CSS, and HTML
• You need to share components across multiple applications
• You require a highly customized app
• You need to integrate a wide range of components into the app

When to use Angular?

You need to go with Angular in the following conditions.

• Your team has a good grasp on C# and TypeScript
• You want ready-to-use solutions and higher productivity
• You need control over app size
• You need a large-scale and feature-rich app

Who wins in the Angular vs React battle?

Angular is witnessing decent adoption amongst the developer community. React.js has come up with some major changes that empower the developers. Both the technologies have their own pros and cons, and the final decision to choose depends on the purpose of the project.

Both Angular and React.js provide extensive features and capabilities, making them fit for a wide variety of projects. So whatever you choose in the Angular vs React 2022 battle, ensure to select the most appropriate Angular or React.js development company. Because without the help of top Angular and React.js developers, it is not possible to build a quality product.
